"Band of Freaks" (or "bag of fuck"). Used to describe kids who listen to shitty metal bands and have bad hygiene. Usually have greasy/dyed/long-ish hair and wear darker clothes because they're "nonconformists" (ha, right). Very similar to "emo", but they probably want to slit other people's wrists.

"you dumb B.O.F."

"grow up you B.O.F."
